摘要： A compliant, flexible air bearing slider (ABS) reduces the contact forces between the slider and disk, thereby reducing excessive burnishing and wear and increasing the reliability of the slider. According to an embodiment, an ABS has at least one “compliance-enhancing feature” which reduces the bending mode vibration frequency of the slider. By causing the slider to flex, and bringing the bending mode vibration frequency closer to the pitch 2 eigenmode frequency, coupling of the different vibration modes can be obtained. Thus, the different vibration modes can effectively dampen each other and result in reduced contact forces between the slider and disk.
摘要翻译：兼容柔性的空气轴承滑块（ABS）可减少滑块和圆盘之间的接触力，从而减少过度抛光和磨损，并提高滑块的可靠性。根据实施例，ABS具有至少一个“柔顺增强特征”，其降低了滑块的弯曲模式振动频率。通过使滑块弯曲，并使弯曲模式振动频率更接近于本征模式频率，可以获得不同振动模式的耦合。因此，不同的振动模式可以有效地相互阻尼并且导致滑块和盘之间的接触力减小。

摘要： The head of a disk drive has write elements disposed on one protrusion pad that wears away during initial operation to permit reduced tolerances and, thus, reduced spacing between the disk and head, with the read element being disposed on a separate protrusion pad and spaced from the write element pad in the radial dimension. This prevents read element recession during cooling in the absence of write current that could otherwise occur if the read element were located on the same pad as the write head.

摘要： A magnetic recording disk drive has a negative-pitch slider in near-contact or continuous-contact with the disk during reading and writing of data. When the disk is rotating at its operating speed, the slider has its upstream or leading portion located closer to the disk surface than its downstream or trailing portion. Both the leading and trailing portions have air-bearing surfaces that enable the slider to be partially supported above the disk surface. A contact pad that provides no substantial air-bearing support is located at the leading portion and supports or contains the magnetic elements of the read/write head. The contact pad protrudes beyond the air-bearing surface of the leading portion and is in contact with the disk. For near-contact recording the contact pad partially wears away during an initial wear-in period. For continuous-contact recording the contact pad is wear-resistant and remains in substantially continuous contact with the disk during reading and writing of data.

摘要： A slider-disk interface tester for measuring the friction force at the interface uses a “negative-pitch” slider in contact with a rotating disk. The tester includes a base that supports a motor for rotating the disk and an actuator for supporting the slider and moving it to a desired radial location on the disk surface. The slider is connected to the actuator by a rigid arm and a suspension like the suspension used in disk drives. When the disk is rotating, the negative-pitch slider has its upstream or leading portion in contact with the disk surface and its downstream or trailing portion not in contact with the disk surface. A contact pad is located at the leading portion of the slider and is in contact with the disk surface. The tester includes a friction-force sensor and associated measurement circuitry, such as strain gauge, piezoelectric and temperature sensors, and is located at one of several locations on the rigid arm, suspension or slider.

摘要： An air bearing burnish slider burnishes very small asperities and cleans the loose particles that adhere to the magnetic recording media. The slider applies a controllable contact force to effectively burnish disk asperities or partially attached particles. In addition, the slider cleans the loose particles effectively while flying in a stable fashion. In a low pitch design, diagonal rails push particles away from the disk surface and trailing edge pads contact the disk at lower linear velocities. Rail pads retain loose contamination and debris in their pockets and burnish asperities. Another design provides a milder burnish force and flies in a high pitch configuration. The trailing edge pads provide stable contacts and the rails help in sweeping away debris. In both designs, the contact forces can be controlled by adjusting linear velocities. A step taper at the leading edge provides a pitch-producing lift force.

摘要： A magnetic recording disk drive achieves continuous contact recording with a head-suspension assembly that compensates for the moment generated from an adhesive force between the head carrier or slider and the disk. The slider pivot point, which is the point where the load force is applied to the flexure that supports the slider, is located closer to the front end of the slider than the net force applied by the air-bearing surface of the slider when the disk is rotating at its operational speed. This assures that the net air-bearing force generates a moment about the pivot point to partially counteract the flexure moment and the moment generated from the adhesive force between the disk and the slider's contact pad.
摘要翻译：磁记录盘驱动器通过头悬挂组件实现连续接触记录，该组合补偿从头托架或滑块与盘之间的粘合力产生的力矩。滑块枢转点，其是负载力被施加到支撑滑块的挠曲件的点，位于比由滑块的空气轴承表面施加的净力更靠近滑块的前端的位置，当盘正在以其运行速度旋转。这确保净空气轴承力围绕枢转点产生力矩，以部分地抵消弯曲力矩和由盘和滑块的接触垫之间的粘合力产生的力矩。
